The GT35 car has external wastegates, but a set up that breathes well with internal wastegates will offer a more steady boost, than a set up with smaller pipes that have pressure drop. Here is some examples of stock turbo, stock engine set ups that have small pipes vs. big pipes.
All 4 cars have completely stock engines and stock turbos, all 4 cars have over 100K miles on the engines, all 4 cars are running 91 octane, all 4 cars are running similar mid 11 air fuel ratios.
All cars have boost controllers, all are running in the 14 PSI to 15 PSI range.
2 of the cars have 2.5" full exhaust, larger intercoolers, single pop.
2 of the cars have 3" full exhaust, 2.5" intercooler pipes and Ash massives, selin dual pops, MSP manifolds.
On the breather cars, notice how fast the boost comes up, and how well it holds boost compared to the 2 more restricted cars.
